A ready-reference guide: essential terms, and the rules that keep turpentine out of your glass.
Before “what is bourbon,” there’s an older question: says who? This is the land of the free, settled by whiskey-fueled cowboys slamming rotgut through saloon doors. Bureaucrats in Washington don’t get to tell us what we can drink and what to call it… right?
Yeah, they do.
| Bourbon must be made in Kentucky | False. It must be made in the U.S.A. Kentucky isn’t required — but it does dominate (~95–97%). Think Springsteen: “Born in the USA.” |
| Bourbon must be aged at least 2–4 years | False. No minimum age — unless it’s “straight” (then 2 years min; under 4, the age must be stated). |
| “Straight” bourbon and rye contain no additives | True. No added coloring, flavoring, or other spirits. Only water to adjust proof. No staves, spirals, or inserts. |
| “Small batch” and “single barrel” are legal terms | False. Marketing terms, with no legal definition. |
| Bourbon barrels can be reused for bourbon | False. Straight bourbon must be aged in new, charred oak — effectively once-used only. |
In Scotland, Japan, and Canada, it’s whisky. In the United States (and Ireland), it’s whiskey — generally. Except when it isn’t: the federal regulations themselves use “whisky,” and note the word “may be spelled as either ‘whisky’ or ‘whiskey.’”
For this Handbook, we’re Team “E.” It feels more patriotic. And bourbon’s as American as apple pie — spiked with, well, bourbon.
Government bureaucracy controls just about everything about bourbon. (Because if it didn’t, apparently we’d all be drinking turpentine. On Sunday.) The federal framework, minus the migraine:
Under 27 CFR § 5.143, whisky is an alcoholic distillate from a fermented grain mash, distilled below 190° proof, stored in oak, and bottled at not less than 80° proof. Bourbon narrows it: at least 51% corn, distilled to no more than 160°, stored in charred new oak at no more than 125°, no added anything but water.
All bourbon is whiskey, but not all whiskey is bourbon.
